What does lineHeight represent in textmeshpro?

Given a piece of text I get the value for the lineHeight of line 0 using

    TextMeshPro text = "some text";
    print(text.textInfo.lineInfo[0].lineHeight); // Some value

Does the value returned here include ascenders and descenders or just the x-height? (see picture for reference) alt text
i couldn’t find a clear answer looking at the API documentation.

Got an answer from Stephan_B himself and I quote:

“LineHeight = Ascender - Descender + lineGap”
Where these properties are defined in the font file.
